High-efficiency anticorrosive paint containing polyelectrolyte brush and preparation method of high-efficiency anticorrosive paint

The invention discloses an efficient anticorrosive coating containing a polyelectrolyte brush and a preparation method of the efficient anticorrosive coating, the efficient anticorrosive coating containing the polyelectrolyte brush comprises a film-forming substance of waterborne epoxy resin and a curing agent and a nano reinforcing filler of a spherical electrolyte brush, and the addition amount of the polyelectrolyte brush is 0.01-1wt.% of the anticorrosive coating. According to the invention, a maze effect is favorably formed to inhibit diffusion of corrosion ions, and carboxyl of polyacrylic acid of brush hair of the polyelectrolyte brush is promoted by an amine curing agent, so that the crosslinking density of the water-borne epoxy resin is improved, and the porosity of the water-borne epoxy resin is reduced. And meanwhile, the polyelectrolyte brush is provided with a plurality of dense bristles, so that the crosslinking density of the water-borne epoxy resin can be better improved, and the corrosion res
